Process to wash polymers contaminated with polychlorinated biphenyls (PCBs)
Abstract
A process of washing plastics contaminated with polychlorinated biphenyls (PCBs) is provided to reduce the concentration of the PCBs. A two-step process includes a first washing step using a selected washing solution or solvent, such as, a non-flammable solvent, and followed by a second step using thermal desorption. The two-step process enables reducing the concentration of PCBs in polymers, such as recovered from shredder residue, for example, to as low as 0.253 PPM. One of the preferred solvents is Perchloroethylene.
